Changes coming to Miami Dolphins lineup

The Dolphins are back at work as they prepare for the Arizona Cardinals and there are changes afoot in the lineup.

Seems second-year man Ikechuku Ndukwe is the choice to replace injured Donald Thomas at the starting right guard position. Thomas, you will recall, is out of the season with some unidentified foot injury.

Also today, Ronnie Brown is getting work in practice ahead of Ricky Williams at the running back spot. While this does not guarantee a change at the starting RB spot, it is a departure from the past couple of weeks when Williams was getting most of the first-team work.

I am also told the team is trying to find a place for Ernest Wilford to be active for Sunday's game but a final decision on that has not yet been made. Seems if this happens, Derek Hagan may be inactive -- but again, that is not decided yet one way or the other.
